About this 3D model

Have more hoses to your NILFISK AERO 20/MULTI II 30T vacuum cleaner? Let's couple them! This adapter was tested with Nilfisk Aero 20 hoses, at the end was hose from Nilfisk Multi II 30T, which I currently use. PETG, 25% infill, 0,4mm nozzle... No supports needed, print it with with wider end down. This adapter was born in a pain, at 4th attempt it is ok. Problem was with locking. Now it seems to be OK. For a case it will be hard to decouple, there are 2 small holes for a nail, to help decouple. It also visually helps with orientation while coupling. Filament: Devil Design PETG “Super Blue”
